| For those of you who build custom stuff and need a different length belt than stock, how do you determine the correct length? On my murray I've swapped pulleys, both 5" and I changed the clutch setup to a design that needs a longer belt. The stock 96" belt is way too short, it's tight before I even get it on the motor pulley, tight just against the motor shaft. I put all the pulleys on and released the clutch and used rope to measure and came up with 98". This is obviously too short since the small rope fits into the V notched pulleys tighter than a belt does. So I'm kinda stuck, especially since I plan to order the belt online, much cheaper. So is there a foolproof way to get this measurement? | |

| Stock is 96" I think. Then I swapped the double pulley clutch from a hydro murray onto it which requires more length.
